SHAVING BRUSH Filed April 28, 1932 fluor/mm3 Patented Mar.l 7, 1933UNITED STATES PATENT OFFICE Application led April 28, 198B. Serial No.608,057.

This invention relates to shaving brushes, and it is an object of theinvention to provide a brush of this kind of a fountain or reservoirtype and which embodies a plunger or piston for effecting the desireddeliver of the shaving cream or the like to the brus proper.

It is primarily an object of the invention to provide a device of thiskind wherein a normally closed valve is employed to control the desireddischarge of the shaving cream or the like together with means operatingas a result of the pressure exerted by the follower or piston toautomatically open said valve and thus avoiding a second operation forthis purpose.

The invention consists in the details of construction and in thecombination and arrangement of the several parts of my improved shavingbrush whereby certain important advantages are attained and the devicerendered simpler, less expensive and otherwise more convenient andadvantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitelyclaimed.

In order that my invention may be the better understood, I will nowproceed to describe the same with reference to the accompanying drawing,wherein Figure 1 is a view partly in longitudinal section and partl inelevation of a shaving brush constructe in accordance with an embodimentof my invention;

Figure 2 is a sectional view taken substantially on the line 2-2 ofFigure 1.

As disclosed in the accompanying drawing, 1 denotes an elongated tubularmember constitutin a handle for the brush and which has its outer orrear end closed by a cap 2 held in applied position in any preferredmanner. This member 1, as particu- .larly illustrated in Figure 2, isoval 1n cross section for a purpose to be hereinafter mentioned.

Arranged within the opposite end portion of the member 1 is a brush Bincluding a back 3 snugly fitting within the member 1 and 50 whichcarries in a conventional manner the brush fibres 4. This back 3 isprovided substantially axiall therethrough with an opening 5 continue byan outwardly disposed vnipple 6. This nipple 6, as illustrated in Figure1, 1s also continued through the opening 55 5 to provide a liningtherefor and also to afford an effective inwardly facing valve seat 7.

The outer portion of the nipple 6 has engaged therewith in aconventional manner a flexible extension 8 directed outwardly within thecentral portion of the fibres of the brush B,lsaid extension 8 readilyielding when the brush is in use so as to offer no hindrance orobstruction to the required ilexibility of the fibres.

Freely disposed within the member 1 through the cap 2 is an elongatedrod 9, the outer or exterior end of which carrying an enlargement orhead 10 whereby said rod 9 7' may be readily and conveniently rotated.

The inner or inserted end portion of the rod 9 is inwardly beveled toprovide a valve end 11 for coaction with the valve seat 7 and said valveend 11 is normally maintained in engagement with its seat 7- through theinstrumentality of an expansible member 12. This member 12 is hereindisclosed as a coil spring surrounding the rod 9 and interposed betweenthe applied cap 2 and an annular flange or enlargement 14 carried by therod 9. The head or enlargement 14 is in close proximity to the appliedcap 2 and the rod 9 in advance of or beyond the enlargement or head 14is threaded, as indicated at 15,and said threaded portion 13 isoperatively directed through the central portion of a follower or piston16 snugly fitting within the member 1. The cross sectional configurationof the member 1 provides effective means for holding the follower orpiston 16 against rotation within the member 1.

The inner or .inserted end of the rod 9 at its axial center is providedwith a forwardly directed pilot arm 17 to facilitate the valvel end 11of the rod 9 finding its seat. The wall of the member 1 in closeproximity to the applied brush back 3 is provided with a filling opening18 defined by an outstanding 100 flange 19 and which opening is adaptedto be closed by a conventional plug 20.

When it is desired to lill the member 1 with shaving cream or the like,the plug 20 is `removed and the screw end of a conventional collapsibletube is engaged therein and the cream within such tube is forced intothe member 1.

It is to be understood, however, that before this is done the rod 9 isrotated in a direction `to fully retract the piston or follower 16.

After the member 1 has been filled with paste the plug 20 is applied andthe brush is then ready for use.

In using the brush requisite rotation is given to the rod 9 to cause thepiston or fol lower 16 to move in a direction toward the brush B and asa result of the pressure imposed upon the cream or the like within themember 1 upon the valve end 11 the rod 9 will be caused to moverearwardly against the action of the expansible member or spring 12resulting in the valve end 11 unseating suicient to permit the passageof the cream out through the opening 5, nipple 6 and cxtension 8 intothe fibres 4 of the brush. AS the pressure within the member 1 isreleased the member or spring12 will act to automatically return thevalve end 11 intol closing engagement with its seat 7.

It is also to be stated that in order to accommodate the different sizesof necks of collapsible tubes of the different popular makes ofshaving-cream, suitable adapters may be employed. The brush B may also'be of a type to allow the same to be removed when desired for placementor the like.

From the foregoing description it` is thought to be obvious that ashaving brush constructed in accordancewith my invention is particularlywell adapted for use by reason of the convenience and facility withwhich it may be assembled and operated, and it will also be obvious thatmy invention is susceptible of some change and modification withoutdeparting from the principles and spirit thereof and for this reason ldo not wish to be understood as limiting myself to the precisearrangement and formation of the several parts herein shown incarrying-out my invention in practice except as hereinafter claimed.

I claim 1. A device of the character described consisting of anelongated tubular member, a brush extending within one end portion ofthe member, said inserted portion of the brush having an opening topermit delivery therethrough to the fibres of the brush, the innerportion of such opening constituting a valve seat, a rod freely disposedthrough the opposite end portion of the member, the inserted end of therod constituting a valve for coaction with the valve seat, an expansi'er threaded upon aeeaeea ble member lwithin the tubular member andcoacting with the rod and a wall of the tubular member for normallymaintaining the valve end of the rod in closing engagement with thevalve seat, and a follower threaded upon the rod and moving therealongupon rotation of the rod, the pressure created by the follower upon thecontent of the tubular member upon rotation of the rod in one directionbodily moving the rod and follower against the tension of the expansiblemember to allow the valve at the inserted end portion of the rod to moveaway from its seat,said rod and follower bodily moving in the oppositedirection under the action of the expansible member as the ressure onthe content of the tubular mem er decreases to return the valve of therod to its seat.

2. A device of the character described consisting of an elongatedtubular member, a brush extending within one end portion of the member,said inserted portion of the brush having an opening to permit deliverytherethrough to the fibres of the brush, the inner portion of suchopening constituting a valve seat, a rod freely disposed through theopposite end of the member, the inserted end portion of the rod beingbeveled and constitutng a valve for coaction with the valve seat, anexpansible member within the tubular member and coacting with the rodand a wall ofthe tubular member for normally maintaining the valve endof the rod in closing engagement with the valve seat, and a followerthreaded upon the rod and moving ing therealong upon rotation of therod,'the pressure created by the follower upon the content ofthe tubularmember upon rotation of the rod in one direction-bodily movingthe rodand follower against the tension of the expansible member to allow thevalve at the inserted end portion ofthe rod to move away from its seat,said rod and follower bodily moving in the opposite direction under theaction of the expansible member as the pressure on the content of thetubular member decreases to return the valve of the rod to its seat.
